Bulk hackery, that's how.
See http://lists.debian.org/debian-boot/2004/05/msg03665.html
This worked for me insofar as I got GRUB to install, but I didn't seem to
have a menu.lst, despite the above saying I should have. I had to do further
hackery at a grub prompt along the lines of:
root (hd0,0)
kernel /vmlinuz ro root=/dev/md0 md=0,/dev/foo,/dev/bar
initrd /initrd.img
boot
where /dev/foo (and optionally /dev/bar) were the members of my /dev/md0.
(Optional, as in my case, I was trying to build a degraded RAID1).
If you have an md1, add "1,/dev/baz,/dev/blaz" to the above incantation.
Once I managed to boot into the sucker, I recreated my initrd for good
measure, and ran update-grub, and it built a menu for me. It wasn't for the
faint of heart at all.
